Question

The pressure p at the bottom of swimming pool varies directly as the depth d of the water. If the pressure is 125 Pascal when the water is 2 meters deep, find the pressure when it is 4.5 meters deep.
214.8


Equation➡ p=kd
125=k(2)
125/2=2k/2
125/2=k or K=125/2
P=(125/2)(4.5)
P=281.25 ⬅Answer
